does there exists any sofware to manipulate/view signals/slots in graphical view?

Designer operates on forms. The rest is pure hand written code. Designer has no knowledge of it, so it won't allow any "graphical" way of connecting signals and slots that were not even defined yet.

Ok, understood, it would be not as simple to do that as I expected, I confused objects with classes.

I guess one could make a tool that would scan class headers to look for signals and slots and then allow generating code for connecting them. But it's a tricky thing and would be prone to errors. It's much simpler to use the auto-connect feature to connect signals and slots according to object names.
